Yes, I thought it was interesting that manillas were initially described onthe show as 'primitive currency' then we discovered they were made in the UK to buy slaves. Also, I'm sure we all learnt about trading with glass beads when the British met 'natives'. Puts a rather different slant on it to know glass beads were traded for slaves.
The English History curiculum really needs to be less 'we stood up to Hitler and Henry had 6 wifes' and our role in the slave trade and the world wide impact of the Empire really need to be covered more (no criticism of teachers there, just the influence of politicians on the curriculum).
